IMPROVEMENT IN HAME-DRESS ING MACHINES.

Specification forming part of Letters Patent No. 222,509, dated December 9, 1879; application filed Tb all whom it may concern Be it known that I, FRANZ KREIN, of the city of St. Louis, in the State of Missouri, have invented a certain new and useful Improvement in flame-Dressing Machines, of which the following is a full, clear, and exact description, reference being had to the accompawill be hereinafterfully described and claimed.

In the drawings, Figure l is a section at :r m,

Fig. 2. Fig. 2 is part in top view and part in horizontal section at m m, Fig. 1. Fig. 3 is a face view of the working clamp to which the hame is clamped when applied to the cutter. Fig. 4 is a top view of the same with the hame shown in dotted lines. Fig. 5 is an edge View of a hame before ironing, showing the swell.

Fig. dis a transverse section, showing a mang ner of holding the hame in the working clamp by means of a claw-dog forced down by a screw. I

A is a frame of any suitable construction,

supporting a table, B.

, O is a vertical cutter-shaft, turning in bearings D D near its upper and lower ends, and steppedin a box, E, having capacity for vertical movement for the raising and lowering of the cutter-head F.

The step-box E is supported by a rod, G, which is itself supported on the short end of a treadledever, H. The treadle lever has a fulcrum at h.

The longer end of the lever H is forced down (to lift the cutter) by means of a treadle, J, connected with the lever H by y a pitman-rod, K, sliding in bearings 70.

Upon the longer end of the lever H may be hung a weight, L, to partly counterbalance the cutter-shaft; but the cutter-shaft must have sufiicient preponderance to insure its descent to the lowest position when the foot of the V workman is removed from the treadle J February 26, 1879.

The cutter, in Fig. 1, is shown in its upper I ficulty I make in the cutter-head, just in advance of each knife, a rounded groove, which allows the escape of the shavings, and whose anterior edge, by proximity to the face of the hame being worked off, prevents slivers tearing in ahead of the knife.

A specific description of the construction of the cutter-head is omitted from this application, as that part of my invention is made the subject of a separate application.

I will now describe the clamp-block to which the blank or undressed hame is clamped for application to the cutter. This clamp-block has a base, 0, which lies flat upon the table and slides easily thereon. The edge 0 of the base 0 is rabbeted, and has the same vertical .outline as the hame O and is arranged to rest against the shank F of the cutter-head, and thus to hold the blank the required dis,- tance from the axis of the cutter-head, so that the cutter will impart the required shape to the hame-blank as it is moved past in front of the cutter-head.

The corner of the cutter-head turns in the rabbeted edge 0, and it is supported upon the lower side thereof. Thus the cutter-head is gradually lifted by the guide edge until it reaches the point of greatest swell, and is then. allowed to descend from that point to the end.

The cutter-head may be at any time raised by the depression of the treadle, as set forth; but this would not give the exact vertical movements imparted by the guide-edge.

The clamp-block has handles P, by which it is operated.

Q Q are arms,in which work vertical clamping-screws R, to clamp the hame-blank in position. The points of these screws may rest directly on the blank, as seen in Fig. 3, or they may bear upon a claw-dog, S, which takes hold of the blank, as seen in Fig. 6.

Itwill be understood that two clamp-blocks will be required-one for each edge of the hameone being made with a concavelveurved guide-face, and the other having a face convexly curved.

The operation is as follows: The hame blank, either sawed or bent into shape, is clamped upon the clamp-block, and one end of the guide-face of the block is made to touch the shank of the cutter-head. The clamp-block is then moved endwise in front of the cutterhead with its guide-face in continuous contact with the shank of the cutter-head. While this movement is taking place the cutter-head is gradually raised by the inclined guide-edge O to the central point of the swell and then allowed to descend to form the swell; or the same object may be accomplished, but less perfectly, by use of the treadle, the same being gradually forced downward and then gradually allowed to ascend again, thus raising the cutter-head and leaving the central part of the hame thicker than the ends, as is required, as

the strain of the trace comes first upon this part.

The shaft 0 is rotated by a belt, T, on the pulley U.

I claim as my invention- 1. The combination of cutter-shaft 0, turning in hearings D D near its upper and lower ends, vertically-moving step-box E, rod G, for supporting same, treadle-lever H, fulcrumed at h, weighted at one end, pitman-rod K, and treadle J, as described.

2. The' sliding clamp-block having curved base 0, whose edge 0 is rabbet-grooved and is of the same vertical outline as the hame O handles I, arms Q, vertical clamping-screws R, and clamp-dog S, as and for the purpose set forth.
